Abstract: A fluid valve has a mobile permanent magnet (10) with its axis aligned with clearance gaps between fixed soft iron core pieces (21,5). Separate coils (20,15) can magnetize one core or the other so as to repel the magnet into contact with the unmagnetized core. The repulsion movement moves a respective valve closure member with respect to a seating (2) or (23). 
     The movement may be such that the magnet 10 abuts an end (19) or (25) of valve closure members which project from the seating on one end of a bore through the respective core (21) or 5, out through the other end of the bore. 
     When neither coil is energized, the magnet stays in the position last commanded, so that both of the two alternative positions are stable and do not consume electrical power. The usual solenoid valve must be energized continuously (consuming power and generating heat) in one of its positions of opening or closing. A pulse thus suffices to change over between the stable states of the valve.

Abstract: An arithmetic frequency synthesizer (24) for generating a bit clock frequency for the flying spot scanner of a digital printer includes means for loading a pseudo-random offset value, accm i , into its accumulator at the start of each scan. The offset values for successive scans pseudo-randomly vary within a range 0 ≦ accm i  < N for all bit clock frequencies required for normal operation of the printer. Thus, the offsets psuedo-randomly phase shift the phase transitions of the bit clock sufficiently to prevent periodic variations in the bit clock duty cycle from spatially aligning with each other in the process direction during the printing of adjacent scan lines. 
     In a printer having a prismatic scanner, a different predetermined pseudo-random offset value is advantageously provided for each facet of the prism (12), whereby the offset value for any given facet can be retrieved from a table look-up memory under the control of a scan counter or the like to be applied to the frequency synthesizer alone or as an initial offset for a polygon signature correction value for the given facet.

Abstract: In an adder control circuit (13), a plurality of adders (10a:10d) are so arranged that a carry bit (Ci) of the adder for calculating low orders of values to be added is inputted to the adder for calculating high orders thereof. The adders (10a:10d) are controlled in response to a clock having a time period which is more than a maximum calculation time period among calculation time periods by the respective adders required for outputting the carry bits, and is less than a total calculation time period of all adders (10a:10d). 
     Therefore the system clock frequency need not be decreased when expanding the bit-width of the adder. 
     The adder control circuit further determines if the carry is still propagating after each clock period. If the propagation of the carry has stopped, the circuit will generate a Valid Signal (14). Only if there is no carry to the higher order adders, and if in these adders no carry is generated, this Valid Signal will be issued and the calculation is finished.
